The effects of a set of stress treatments on gene expression of Chironomus thummi salivary gland cells have been analyzed. Among the treatments assayed, only during recovery from carbon dioxide have we observed a response similar to that previously described after heat-shock treatment: induction of the heat-shock puffs and synthesis of the heat-shock polypeptides. In these conditions, puffing and transcription of telomeric regions were observed, which led to the appearance of the temperature-inducible telomeric Balbiani ring T-BR-III. Other treatments failed to induce the heat-shock response, despite promoting real stress conditions to C. thummi larvae or salivary gland cells.
分析了一组应激处理对摇蚊唾液腺细胞基因表达的影响。在所检测的处理中，只有在从二氧化碳恢复过程中，我们才观察到类似于先前热休克处理后所描述的反应：热休克胀泡的诱导和热休克多肽的合成。在这些条件下，观察到端粒区域的胀泡形成和转录，这导致了温度诱导型端粒巴尔比亚尼环T-BR-III的出现。尽管其他处理对摇蚊幼虫或唾液腺细胞造成了实际的应激条件，但未能诱导热休克反应。
